我有 silverlight 应用程序，但出现此错误：

[Async_ExceptionOccurred]
Arguments:

See http://go.microsoft.com/fwlink/?linkid=106663&Version=5.0.61118.00&File=System.dll&Key=Async_ExceptionOccurred INNER >System.ServiceModel.CommunicationException: [CrossDomainError]

我有 WCF 服务并且在浏览器上运行良好。我在根站点上有如下 clientacesspolicy.xml （WCF 服务所在的位置）

<?xml version="1.0" encoding="utf-8" ?>
<access-policy>
  <cross-domain-access>
    <policy>
      <allow-from >
        <domain uri="*"/>
      </allow-from>
      <grant-to>
        <resource path="/" include-subpaths="true"/>
      </grant-to>
    </policy>

  </cross-domain-access>
</access-policy>

我做错了什么？有谁能够帮我？

编辑 ：

在我的本地主机上工作正常，但在服务器上却不行。提琴手似乎还可以，没有错误。

我是否缺少一些 IIS 配置？

我遇到了同样的问题，并在这篇文章之后让我的工作：使服务跨域边界可用。

我必须进行如下更改，有人在该文章的底部发表了评论：

<allow-from http-request-headers="*">
